Napco Security FW-4 4 Wire Photo Electric Smoke 12/24V

Napco Security Alarm FW-4 4 Wire Photo Electric Smoke Detector is engineered for optimal fire safety and reliable performance. This advanced smoke detector utilizes dual bi-colored LEDs to indicate its operational status, flashing green during standby and shifting to red when smoke is detected. With its low-profile design at just 1.8 inches high, the FW-4 is both unobtrusive and effective. Featuring a built-in thermal heat sensor, this model accurately detects a wide range of fire types, making it a versatile addition to any safety system. Its non-directional smoke chamber and vandal-resistant locking mechanism enhance security, while the automatic sensitivity window verification ensures compliance with NFPA 72 standards. The FW-4 operates on a voltage range of 12 to 24 VDC and is compatible with UL-listed fire alarm panels. Additionally, it boasts RF and transient protection, minimizing the chances of false alarms. The removable smoke labyrinth allows for easy cleaning or replacement, ensuring the detector remains in peak condition. Whether used in residential or commercial settings, the Napco Security Alarm FW-4 provides peace of mind with its reliable smoke detection capabilities and robust features. Enhance your fire safety strategy with this dependable smoke detector.

4 Wire Photo Electric Smoke 12/24V

The Firewolf FW-2 advanced photoelectric smoke detectors utilize two bi colored LEDs for indication of status. In a normal standby condition, the LEDs will flash green every 3 seconds. When the detector senses that its sensitivity has drifted outside the UL Listed sensitivity window, the LEDs will flash red every 3 seconds. When the detector senses smoke and goes into alarm, the status LEDs will latch on red.
